 That is the correct form of paths.  Device names can change at runtime
 so they are not part of the object path as exposed over D-Bus.
 
  2/ If I get the Device object with path
  like /org/freedesktop/NetworkManager/Devices/eth0, I can get the object
  but Introspectable interface gives me no interface at all on this
  object. Strange...
 
 Right, because that's not actually an object that NetworkManager exports
 over D-Bus, which is why you won't get any introspection information.
 It could be a bug in the Python dbus bindings that you get an object
 here at all, but the Python bits us lazy bindings so they'll only look
 up the introspection information when you need it, which can be later
 than when you create the Interface object.
 
 In the end, the bug is in dbus-glib 0.94 and fixed in 0.96.
